Manufactured from high speed steel (HSS), this end mill features a spiral flute geometry with a 30-degree helix angle and an uncoated finish. The mill diameter measures 0.125 inches with a 0.375-inch length of cut and a 3\/8-inch shank diameter. The overall length (OAL) is 2-5\/16 inches. The centercutting design allows plunge milling directly into the workpiece, making it suitable for both slot milling and keyway operations on manual mills and CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in general-purpose metalworking shops, tool rooms, and maintenance environments where small-diameter slot and keyway cutting is required. The HSS construction handles a broad range of ferrous and non-ferrous materials at conventional cutting speeds. The 0.125-inch diameter makes it appropriate for fine keyway work on small shafts and precision components. Machinists, toolmakers, and maintenance technicians are the typical users of this size range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125-inch mill diameter for precise small-slot and keyway cutting\u003c\/li\u003e\n\u003cli\u003e2-flute spiral design improves chip evacuation during slotting operations\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle balances cutting efficiency and edge strength\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry permits direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eUncoated high speed steel construction suitable for general metalworking materials\u003c\/li\u003e\n\u003cli\u003e3\/8-inch shank diameter fits standard collets and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard keyway end mill for use in manual knee mills, CNC machining centers, and toolroom mills equipped with collets or end mill holders accepting a 3\/8-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and operation should be performed by a qualified machinist or toolmaker. Ensure the machine spindle is fully stopped and the power is locked out before mounting or removing the end mill. Secure the shank firmly in a clean, undamaged collet or end mill holder to the tool holder specification; an improperly seated tool can cause runout and premature cutting edge failure. Use appropriate cutting speeds and feeds for the workpiece material, and verify adequate coolant or lubrication to extend tool life when cutting ferrous materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E116300801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730614354226,"sku":"E116300801","price":34.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ba069a1a9937ee5e8e079b53fdedb5a.jpg?v=1788720321","url":"https:\/\/voomisupply.com\/products\/hertel-e116300801-keyway-end-mill-0-125-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
